Relative abundance of bacteria at phyla level in each group

Groups	BC(%)	BH(%)	BL(%)	BM(%)	NC(%)
Spirochaetae	0.32	1.40	26.37	7.11	1.76
Firmicutes	2.78	25.38	1.20	1.57	3.18
Fusobacteria	17.28	8.20	14.86	16.00	18.23
Proteobacteria	58.55	7.40	21.54	51.15	23.74
Other	0.75	1.91	0.30	0.11	0.19

Numbers represent the relative abundance of the predominant bacterial phyla. NC, fishes were fed with basal diet; BC, fishes were fed with pellets covered with B.s-CotC spores (1 × 10⁸ CFU g⁻¹ pellets); BL, BM, BH, fishes were fed with pellets covered with dosages of 1 × 10⁵, 1 × 10⁸, 1 × 10¹¹ CFU g⁻¹ pellets of B.s-CotC-CsPmy spores, respectively
